TRAVERSING OR BUILDING DEVICE FOR FLIERS.

SPECIFICATION forming part of Letters Patent No. 661,019, dated October 30, 1900.

Application filed July 17, 1900. m'erial No. 23,945. (No model.)

To aZl whom it may concern:

Be it known that I, CHARLES STODART Mc- CONNAN, a subject of the Queen of Great Brit ain, residing in Liverpool, in the county of Lancaster, England, (whose postal address is 305 Edge Lane, Liverpool, England,) have invented certain new and useful Improvements in Traversing or Building Devices for Fliers, of which the following is a specification, and for which application has been made in Great Britain, (provisional application only,) dated November 11, 1899, No. 22,529.

This invention may be used for fliers employed in spinning and twisting and in cordage manufacture and for the spinning, twisting, or the like operation of any material in which the fibers of that material are strong enough for the purpose to be described. I'

consider my invention most applicable to cordage manufacture, principally to the forming of rope-strands and rope-making, and very suitable for making heavy cords and the like.

The invention will be described for a flier used in the spinning of rope-yarn, which 'will serve to illustrate my invention.

In the accompanyingdrawings, Figure 1 is a sectional elevation of a horizontal flier, showing the application of my invention; Fig. 2, a cross-section, on an enlarged scale, of the device for traversing the guide-pulley; Fig. 3, a longitudinal section thereof, and Fig. 4 a plan; Fig. 5, a detail View of a modification of the yarn-guide pulley; Figs. 6 and 7, my invention applied to a traverse-ring. Fig. 8 is a detail view showing a counterbalanceweight for the unthreaded rod of the flier. Fig. 9 is a detail view showing an arrangement for securing the requisite friction or grip between the yarn and the pulleys, so as to insure the driving of the traversing-motion by the running of the yarn. Figs. 10 and 11.are respectively a side elevation and a plan view of the carrier, showing a modification of the arrangement for insuring the driving of the traversing-motion by the running of the yarn.

My improvement is applied to apparatus of that kind in which the bobbin is not traversed, but the pulley or other device which conducts the yarn to the bobbin is made to move backward and forwardlongitudinally with the bobbin-axis, and thus wind the yarn thereon. The manner in which the pulley is traversed so as to wind the yarn equally upon the bobbin constitutes, essentially, my invention. 7

The flier consists of the usual end disks A, with journals held together by two arms B, secured by nuts at ends in the usual way. Either or both of these flier-arms B, Whi('h are fixtures in the end disks, have a right and left hand traverse-screw b, with continuous threads cut on their outside diameters for the requisite amount of their length.

l is a sleeve or carrier, preferably solid, having a rotary bush D fitting and capable of sliding easily on the traversescrew 12. This bush D is secured in place by a shoulder at one endand by a nut 01 and washer at the other, so that it cannot separate from the sleeve.

E is a traverseweb or tongue mounted in and secured bymeans of nuts 6 in a split boss on the bush D, said web or tongue engaging in the threads of the traverse-screw b, so that the bush on being rotated will travel to and fro along the screw and set up a traversing movement of the carrier.

. F is a worm-wheel firmly secured to and concentric with the bush D. I

G is a'bracket on carrier O, on which there is mounted a traverse-spindle g, and on this traverse-spindle there is mounteda worm H, whichengages in the worm-wheel F. At one end of the spindle G is a yarn-guide pulley or sheave I, made solid with correctly-shaped groove to enable the material to properly grip it, which conducts the yarn to the bobbin.

On the carrier or sleeve 0 thereis cast or otherwise formed a lug K, so, shaped as to slide on the rod 7.; as the sleeve slides to and fro on the traverse-screw b. This rod is is fixed in close proximity to and parallel with the flier-arm B and held to each end disk of the flier, preferably in the same manner as the flier-arms are fixed-namely, by screwing the ends of same and holding with nuts. The purpose of this rod or guide is to resist the pull of the yarn and to hold and retain the carrier with its yarn-guide in the required position. It forms, however, no obstacle to the carrier moving backward and forward longitudinally the length of the bobbin or its essential on account of the high speed I may run this flier.

N is the yarn or other material being twisted.

If both the flier-arms be threaded and fitted with carriers, the flier is counterbalanced, one side being no heavier than the other. If, however, only one flier-arm be threaded, then in that case the un hreaded one B is counterweighted at 2, as seen in Fig. 8, so as to balance the other arm and its traversing device.

The mode of action is as follows: The yarn N passing from the capstans runs over guidepulley L, mounted on a pin at one end of the flier-arm Bin the usual way, and then passes over the aforesaid guide-pulley I to the bobbin M. Now this pulley has its groove 2 so formed that the yarn while running over its periphery will also drive it and impart to the aforesaid spindle g a rotary motions This spindle will in turn by means of its worm H drive at a slower speed the aforesaid wormwheel F, which being fixed to the bush will rotate it. The bush holds the traverse web or tongue E, that works in the continuous threads of the right and left hand traversescrew on the flier-arm, and thus as the bush is rotated by the guide-pulley it moves to and fro along the screw on the flier-arm traversing the carrier C with its yarnguide pulley longitudinally with it, and thereby traversing the yarn on the bobbin, so that it will be wound equally along the latter. The carrier itself, with its yarn-guide, is prevented from being dragged over by the pull of the yarn by means of the guide-bar l0 and lug K or ring 0", as herein described, or other convenient means, while the bush D is free to rotate inside the carrier, thus insuring that the guide-pulley shall move up and down longitudinally of the traverse-screw in a straight line. It will be seen, therefore, from the above description that the motion of the pulley I to and fro longitudinally of the flier (listributes the twisted material equally along the bobbin, and thus motion is produced not by any revolution of the right and left hand screw, which in my invention is held perfectly stationary, but by the running of the yarn or other material itself. Gearing is detrimental to high speeds, and by this invention, there being no gearing required to drive the traverse-screw, I am able to secure a higher speed, and, furthermore, the machine is considerably simplified and is much shorter in length than in cases where the bobbin is made to travel in the direction of its axis.

In Fig. 5 a modification of the yarn-guide pulley is shown. This is used in case the material being twisted is so fine that it will not drive my traversing mechanism. on solid pulley I of itself. This consists of the pulley I, split at t" and provided with a spring I, which can be adjusted by means of a thumb-nut Q, thus enabling the requisite grip between the yarn and the pulley to be obtained.

If desired, there may be more than one groove in the pulleys I and L and the yarn or other material taken several times backward and forward over these pulleys, as shown in Fig. 9, thus insuring the driving of the traversing-motion by the running of the yarn. In such case the pulley I has by preference two V-shaped grooves and the pulley L, the same. The yarn is taken from the capstans to one groove on pulley L, passed partly around it, and carried to a groove on pulley I, then returned to the other groove in L, and forward again to the groove in I, and from thence to the bobbin. Instead of the pulley L having two or more grooves it may have a single groove and a loose pulley L with grooves provided on the carrier 0, adjacent to the pulley I, as shown in Figs. 10 and 11. The pulley L is loose on the pin L which is screwed into a small post L cast or attached to the carrier. The yarn N is run from pulley L around one groove of pulley I and then back to a groove in pulley L and so forward again to the other groove in pulley I, and from thence to the bobbin.

Instead of using the guide-rod for holding the carrier in position I may employ a traverse-ring R, arranged with my traverse motion as shown in Figs. 6 and 7 of the accompanying drawings, wherein the same letters of reference apply to the same or like parts throughout. B is the bobbin end, S the spindle, and B and B the flier-arms, one of which, B is plain and the other, 13 formed with a right and left hand screw with continuous threads. The carrier 0 is fitted in a sleeve at one side of ring R and secured in place by a nut 0, while inside the carrier is the bush 'D on the flier-arm B, and on this bush is secured the worm-wheel F. I is the yarn-guide pulley, and N the yarn or other material being wound. The opposite side of ring R has mounted within its sleeve an eccentric bush T on the plain flier-arm B This eccentric bush allows for adjustment, as if'the arms B or B expand owing to centrifugal force and the ring is traveling on themiddle portion of the flier, the bush T being loose, said bush turns automatically partly around and adjusts itself, preventing the ring R from jamming on the flier-arms and permitting the easy sliding of the ring Rthat is to say, the point at mid-length of each flier-arm will of course expand the most and all points along each half-length of the flier-arm will gradually expand less until the ends of the flierarm are reached, where there will practically be no expansion due to centrifugal force bush '1 and the sleeve in which it is fitted in' such manner that when the ring is in that position where the flier-arms do not eXpandnamely, the endsthe ring will be automatically returned to its normal position and adjust itself continually according to the position of ring R on the flier. The eccentric bush T and its containing-sleeve are of such a length and weight as to counterbalance my traverse-movement on the opposite side of the It will be readily understood that my traverse-motion, as hereinbefore described, may be applied with advantage to existing machines.

I declare that what I claim is 1: An apparatus for spinning or twisting yarns or other material, comprising fliers, a bobbin arranged between them, a guidingpulley adapted to be moved backward and forward along one of the fliers for conducting the material to the bobbin, mechanism operated by the said pulley for feeding the same longitudinally with respect to the bobbin, whereby the material will be fed evenly from one end of the bobbin to the other, substantially as described.
